A neighbor of mine has some ammo thats +P+ IN 9MM. I've been wanting to get some good penetrating ammo for my Glocks, in a 40 and 9mm. I figured some fmj in a +P would be fine. But this guy has some +P+ in 9mm. Is this stuff to powerful for Glocks? I don't want to tear my guns up. The brand of ammo is called Bufalo Bore. What do you Glock people think about this?
